As part of my laboratory experience i will handle many chemical substances and manipulate specialized laboratory equipment. Many of these substances pose a health risk if handled improperly, while some of the laboratory equipment can cause severe injury if used improperly. This experiment is a guide to the safe laboratory practices i will use throughout this course in handling reagents, transferring liquid and solid reagent from one apparatus to the other , heating reagents and to distinguish Bunsen burner flame.

The prefix " chroma, " which suggests " color, " comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment, chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids, the building blocks of proteins. The proteins of all living things are composed of 20 different amino acids. The experiment aimed to separate amino acids using the technique of paper chromatography and to identify the color reactions of different amino acids which helps to identify the unknown Amino acids using detection reagent. In this experiment, we investigate the different properties of Amines, Amides, Aromatics and Thiols of Amino acids. We also investigate their solubilities in water and in aqueous acid; how are they prepared and the different chemical reactions they undergo. The mixture of the unknown is found to contain Leucine, Alanine, and Tryptophan. We know that the unknown had leucine as there was a spot in the same line of the chromatogram as leucine section. There was a similar stain(in shape and height) in the unknown to that of Alanine therefore we know that Alanine was in unknown. There was also another stain in unknown of the same height and shape as Tryptophan so obviously this amino acid was also present in the unknown.
